Process For Working On Exercises

Working on the class exercises

The process for working on the exercises is basically the same and goes like this:

shut down the watcher (Control-C in the command line) if it's running
Check out the exercise to work on
```
 git checkout -b ex.01.start origin/ex.01.start
```
If you have previously checked out a branch, you don't need to include the -b -- that is for creating a branch.
Immediately create a working branch for yourself
```
 git checkout -b ex.01.working
```
Push it to your remote repository
```
 git push -u origin ex.01.working
```
Start up the watcher
```
 npm start
```
Work on the exercise. If you feel like it, you can do intermediate commits when you like what you have.
After completing the exercises, save all your work, and update your repository:
```
 git add --all -v
 git commit -m 'end of exercise'
 git push -u origin HEAD
```
